Morning after pill -first time using

My boyfriend and I had sex just a couple days after my period ended, he told me the next day he had a gut feeling he didn’t pull out in time, so I went and got “take action” which is generic plan b. (Yes, we were drinking but hes always pulled out fine even if drinking) so he doesn’t even know for sure if I needed to take this pill, but to be safe I did.

It’s exactly a week later and now I’m spotting, it’s brown on my panty liners, but when I wipe it’s just normal red. It’s pretty light so far but I feel some cramping too as if it’s the start of a period.

I’ve read that this is normal, but can anyone relate to this? My period ended just a couple days before the incident, so does anyone know if that changes the risk of pregnancy? Along with the pill, and now I’m spotting (or lightly bleeding) a week later.

Please don’t comment to tell me that we shouldn’t be having sex without using protection, I just want people to comment if they can relate to this in any way. Thank you
